The system is low cost with long service life, simple operation, compact structure, small coverage and simple installation.
The system vaporizes liquid ammonia, and heats it with a catalyst until decomposition occurs, creating a mixture of gas consisting of 75% hydrogen and 25% nitrogen.
Based on the principle that the molecular sieve adsorbs ammonia and water at different temperatures, high purity gas is produced by heat regenerating through the mixture working at normal temperature.
Air Separation Plant (ASU) adopts molecular sieve air purification, booster turbine expander, medium pressure air cycle refrigeration, double rectification column, full liquid air separation. The control and interlock of complete set plant will be operation in DCS or PLC system, the process will follow the most advanced and common international regulation, and design module on the premise of stable running. The Air Separation Plant including: air filtration system, air compressor system, air pre-cooling system, molecular sieve purification system, double rectification column system, liquid products storage system(if liquid products), instrument control system, electric control system etc.
Widely used in manufacturing the hydrogen and nitrogen at protective atmosphere. Especially for metal heating treatment ,powder metallurgy electronics and others heating.as a ammonia decomposition furnace, it can make hydrogen and nitrogen as protective atomosphere in non-ferrous metal, silicon steel, chrome steel and stainless steel and other metal materials and parts it can be used in bright annealing, in silicon steel it plays a role in decarburization ,in iron processing base powder metallurgy etc.
Equipment Warranty and After-sales Service
Hengda provides the device hardware warranty for one year, the shelf life from the date of acceptance of the equipment is 12 months or 18 months receiving goods, according to which date arrive first. During the period of shelf life, any defects, faults and damage caused by our design, craftsmanship, manufacturing or material defects and any issue caused by our company shall be handled by us without any charge. In the period of quality shelf life, it is free to supply and replace the equipment and spare parts which are not damaged by demand-side. If the equipment have any failure in the operation, supplier’ professional personnel will hurry to the scene within 24 hours when receiving the notice that the demand-side can’t solve the failure. And beyond of shelf-time, Hengda will annual tracking the quality regularly, checking the condition of the equipment operation and also can provide the spare parts long-term.
